SEWER-TRAP.

SPECIFICATION forming part of Letters Patent No. 616,252, dated December 20, 1898. Application filed July 14, 1898. Serial No. 685,921 A (No model.)

To 'ctZZ whom it 71mg/ concern.-

Be it known that I, HENRY PENNIE, a citizen of the United States,residing in New York, (Brooklym) in the county of Kings and State of New York, have invented certain new and useful Improvements in Sewer-Traps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable oth ers skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in sewer-traps designed to cut off the entrance of foul gases into the pipes and connections between house-fixtures and the sewer, and constructed also to prevent the tide-water or overflow from backing up into the house-pipes from the sewer.

The present invention has for its object mainly to make the valve in the trap automatic in opening and closing, whereby it will remain shut and will hold back the waste water in the pipes and connections between the house and the trap until the pressure of such body of water is sufficiently great to lift the valve from its seat, by which operation the waste water will pass through the trap and after having passed the valve will be automatically closed to prevent water or sewer-gas from returning into the housefpipes Another important object is to provide a trap which can be used in a horizontal, vertical, or inclined position, the valve being adapted to be so weighted as to allow lthe same to always remain closed.

The invention consists of several details of construction, substantially as shown in the drawings and hereinafter described and clailned.

In the accompanying drawings, Figure 1 is a vertical sectional view of my trap, showing the same in its horizontal position. Fig. 2 is a cross-section of the same. Fig. 3 is a plan view of the trap, the cover being removed. Fig. 4. is a cross-section of the same, the'cover being removed and the valve taken out. Fig. 5 is a sectional view of the trap, showing the same in its vertical position; and Fig. 6 is a perspective view of the valve.

Referring to the drawings, A represents a trapcasing preferably provided at each end with the ordinary connections for securing the same to sections of pipe in order that the casing may form part of the waste-pipe from the building to the sewer.

Within the casing is fitted a valve B, the side edges of which are formed with sockets or recesses a for the reception of the pivot; pins, which pins are formed with screwthreaded portions b' for half their length and for the rest of their length lwith smooth portions b", the said smooth portions forming the bearings for the valve B. Formed upon the inner side of the casing are the bosses C, one on each side, just Where the screw-pivots pass through the sides of the casing, so as to give the said pivot-pins alonger-bearing, and thereby obviate the liability of the pins becoming loose at this point.

I provide for the valve a counterbalance or weight D, which keeps the valve always upon its seat, except when the pressure of the waste water is great enough to overcome the weight of the said counterbalance. This counterbalance D is provided at its extreme end with a hollowed-out portion E, forming a cup for the reception of lead or other metal, so that the valve may be provided with additional weight when necessary. In the bottom of this cup are formed the holes c, beveled, as shown in Fig. 5 of the drawings, so that when the metal is poured into the cup a portion of the same will pass through the holes, forming heads cl upon said body of metal, and thereby providing means for securely holding the same within the cup E.

The casing is provided With an opening H, and surrounding this opening and a portion F of the casing adjacent to the opening is the flange Il. This ange forms a seat for the dome-shaped cap I, which latter,when secured to the flange, forms a housing in which the counterbalance moves.

G is a brass or other ring inserted within the end of the portion F of the casing and forming a seat for the valve B. This ring abuts against an annular shoulder 7c, which is provided with an inclined outer surface k for the purpose of allowing the waste material to pass through the casing in an uninterrupted manner. By employing a separate ring to form the valve-seat it is found that a much more accurate iit is obtained between the valve and said seat.

In order that free access to the valve and IOO the casing in general may be had for purposes of cleaning and repairing, I removably secure the dome or cap to the flange H. This cap or dome is provided with lugs e upon each side of the same corresponding with the lugs f upon the fiange I-I of the casing, each of said lugs being provided with a hole g for the insertion of bolts h, which, together with the nuts 12, form the means for securing the cap to the casing. A suitable elastic packing J is provided between the cap and the casing for the purpose of making the trap Water and gas tight.

Upon the under side of the cap I is provided a projection or lug K for the purpose of limiting the movement ofthe valve and preventing the same from passing the center.

In manufacturing' these trap-casings I so Weight the valve Within the same that it will justhold the valve upon its seat Without undue force until moved by the pressure of the Water when the said casing is in a horizontal position; butI should the user desire to place the trap in a vertical position or at an inclination it would be necessary to employ sucient additional metal in the cup to bring the same to its seat, it being of course apparent that a weight which would close the Valve When the trap is in a horizontal position would not in all cases be sufficient to close it if used in an inclined or vertical position.

I-Iaving thus described my invention, What I claim is- 1. In a trap, the combination of a section of pipe provided with an opening, said opening and a portion of the casing adjacent to the opening being surrounded by a flange, a cap for said opening, a ring inserted Within the end of said portion forming the seat for the valve, a pivoted valve, and a counterbalance for the valve, provided at its end with a hol'- lowed-out portion adapted to receive Weighting material, substantially as described.

2. In a trap, the combination of a section of pipe provided With an opening, said opening and a portion of the casing adjacent to the opening being surrounded by a iiange, a cap for said opening, a ring inserted within the end of said portion forming the seat of the valve, a valve, and pivot-pins for said valve, substantially as described.

3. In a trap, the combination of a section of pipe provided with an opening, said opening and a portion of the casing adjacent to the opening being surrounded by a ange, a cap for said opening, a ring inserted within the end of said portion, forming the seat for the. Valve, a valve,pivotpins for said valve, and a lug for limiting the movement of said valve, substantially as described.

In testimony whereof I afiix my signature in presence of two Witnesses.
